In mixed woods. Frequent. June to September.

A curious form occurred with the pileus turning very dark when

full-grown. _B. and Br._ POISONOUS. Worthington Smith has tested it by

accident. It produced headache, swimming of brain, burning in throat and

stomach, followed by severe purging and vomiting. _Stevenson._

Gregarious or cespitose. Taste very pungent, a feature which separates

the present from M. oreades. Not coarsely tomentose at the base, as in

M. peronatus, but only downy. _Massee._

I have not known it to disagree with myself or friends. That it may not

agree with some persons is unquestioned. Collectors should carefully

test it upon themselves.

=M. perona´tus= Fr.—_pero_, a kind of boot. =Pileus= 1–2 in. and

more broad, light yellowish or pallid brick-red, then becoming

pale, _wood-color_ or tan, at first fleshy-pliant, then

_coriaceo-membranaceous_, convex then plane, obtuse, flaccid,

slightly wrinkled, even at the disk, _at length pitted, striate at

stuffed, fibrous, tough, attenuated upward, _at length hollow_ and

compressed, _furnished with a bark_, light yellow then pallid,

_cuticle villous_ but separating and reddish when rubbed, somewhat

incurved at the base, where it is _clothed with dense, somewhat

M. peronatus is the wood-cousin of M. oreades. It is still reputed

poisonous by all writers upon the subject, though M.C. Cooke gives it

the benefit of a doubt. The name is given because of the base of the

stem being densely covered with short hairs or a woolly down, and is

thus easily recognized. It is common in woods, among decaying leaves,

especially of the oak, from May until after frosts. It is usually

solitary, but a few individuals are sometimes clustered. It is quite

peppery to the taste, but pleasantly so. I have repeatedly eaten it, as

have my friends. It loses its acridity in cooking, and though the caps

are tougher than M. oreades, they make a highly flavored and delicious

dish. Collectors should carefully test it for themselves.

=M. ore´ades= Fr. _Gr_—mountain-nymphs. Scotch bonnet. Champignon.

becoming pale, absorbing moisture, whitish when dry, fleshy_, pliant,

convex then plane, somewhat umbonate, even, smooth, slightly striate at

the margin when moist. =Stem= 2–3 in. long, 1½ lines thick, _solid_,

very tough, _equal_, tense and straight, _everywhere clothed with a

villous-woven cuticle_ which can be rubbed off, pallid; bluntly rooted

at the base, naked, not villous or tomentose. =Gills= free, broad,

_distant_, the alternate ones shorter, _at first soft_, then firmer,

pallid-white.

_Odor_ weak, but _pleasant_, stronger when dried, _taste mild_. Commonly

growing in circles or rows. _Fries._

=Spores= 6–7×5–6µ _K._; elliptical, 8×5µ _Massee_; nearly elliptical,

white, 7.6–9µ long _Peck_.

Common throughout the states during the summer months after rains, and

in rings, but can be found from May until after frost. If one knows

where the rings are to be found M. oreades can be gathered when

shriveled, and are quite as good, after soaking, as when fresh.

M. oreades must be sought for where the grass is luxuriant. It hides

among it. It is well worthy of the search. Raw, fresh or shriveled, it

is sweet, nutty, succulent when eaten; stewed well it is delicious.

Though tough its consistency is agreeable. The most delicate stomachs

can digest it. The writer saved the life of a lovely woman by feeding

her upon it when nothing else could be retained; and of another, by

feeding Coprinus micaceus, after a dangerous operation. He introduced

these species, together with a few others, into a large hospital in

Philadelphia, where they were used with marked beneficial effect, and

such use is now widespread.

When dried, by exposure to the air or sun, it can be kept indefinitely,

neither losing its aroma or flavor, which it graciously imparts to soups

or any other dish.

Collybia dryophila, Stropharia semi-globata, and Naucoria

semi-orbicularis are sometimes found growing with it. These species are

delicious and harmless.

Lafayette B. Mendel in the Am. Jour. of Physiology, March, 1898, gives

=LENTI´NUS= Fr.

_Lentus_, tough or pliant.

=Pileus= fleshy-coriaceous, pliant, tough and hard when old, persistent.

=Gills= becoming dry, tough, simple, unequal, thin, margin acute,

_toothed_, more or less decurrent. =Stem= when present central,

excentric or lateral, hard and firm, continuous with the flesh of the

pileus.

Growing on wood.

=Spores= somewhat round, even, white.

Distinguished from other coriaceous genera by its serrated and torn

gills.

“The genera Lentinus and Lenzites are found in every region of the

world; their principal center, however, is in hot countries, where they

attain a splendid development. On the contrary, toward the north they

rapidly decrease in number.” Fungi. _Cooke and Berkeley._

In habitat and mode of growth Lentinus closely resembles Pleurotus, and

parallel genera with colored spores. When young the species are

inviting, and when well cooked are meal-giving. They are not delicacies,

but substantials. They dry well. Grated they make soups, and give their

pleasant flavor to any dish.

=L. Lecom´tei= Fr. =Pileus= coriaceous, funnel-shaped, regularly

reflexed, hairy, tawny. =Gills= crowded, pallid. =Stem= short, hairy,

tawny.

Common to the states.

Professor Peck writes to me: “This plant, by reason of its rather tough

substance, has commonly been referred to Lentinus, under the name L.

Lecomtei Schw., but this reference is scarcely satisfactory to me, since

the edge of the lamellæ is scarcely at all serrate as required by that

genus. It seems to me it would go better under the genus Panus. It is

variable—sometimes eccentric or even lateral. It is sometimes called

Lentinus strigosus, but I do not think the two are distinct species,

however distinct they may be in form.” February 26, 1894.

Like all Lentinus the present species is rather tough, yet chopped into

small pieces, well cooked and seasoned, it is quite equal to P.

ostreatus and many others of high renown.

_squamulose_, whitish, often ascending and becoming dingy-brown at the

base, at first furnished _at the apex with an entire reflexed ring_,

_which soon falls off_. =Gills= decurrent (_by no means sinuate_),

narrow, crowded, unequal, toothed like a saw, white.

Somewhat gregarious, even cespitose, thinner and more coriaceous and

regular than L. lepideus B., wholly blackish with squamules. _Fries._

=L. lepi´deus= Fr. _Gr_—scaly. (Plate XVI, fig. 3, 4, p. 52.) =Pileus=

2–4 in. broad, pallid-ochraceous, variegated with adpressed, _darker,

spot-like scales, fleshy_, very _compact_ and firm, _irregular_,

commonly excentric, convex then depressed, but not truly umbilicate,

sometimes broken up into cracks. =Flesh= pliant, white. =Stem= short,

commonly 1 in. long, solid, _stout, very irregularly formed_, almost

woody, tomentose-scaly, whitish, rooted at the base, _at the first

furnished with a veil toward the apex_. =Gills= decurrent, but _sinuate

behind_, crowded broad, transversely striate, whitish, edge torn into

teeth.

Odor pleasant. _Fries._

=Spores= 11×5µ _W.G.S._, 7×3µ. _Massee._

Lentinus lepideus is a sort of commercial traveler. It is common

wherever railroads are. It is partial to oak ties and its mycelium is

injurious to them. It is found upon pine and other timbers. The writer

has collected large clusters of it from oak sawdust. The European plant

is noted as “almost always solitary.” In the United States it is seldom

so. It is noted as growing in damp, dark places, but it loves the sun.

As a food it is about on a par with P. ulmarius, not as tough, but

harder when old. It is a reliable species from spring until late autumn,

is persistent and dries well. It is neat, handsome, prolific. When young

it makes a good dish, and when old can be used to advantage in soups.

=L. cochlea´tus= Fr.—_cochlea_, a snail. =Pileus= 2–3 in. broad,

flesh-color, but becoming pale, somewhat tan, fleshy-pliant, thin,

commonly excentric, imbricated, very unequal, somewhat lobed or

contorted, sometimes plane, sometimes funnel-shaped-umbilicate, but not

pervious, _smooth_. =Stem= solid, firm, sometimes central, most

frequently excentric, sometimes wholly lateral, _always sulcate,

smooth_, flesh-colored upward, reddish-brown downward. =Gills=

decurrent, crowded, serrated, white-flesh-color. _Fries._

Pliant, tough, flaccid, very changeable in form, sometimes solitary,

sometimes cespitose, imbricated, growing into each other. From very

small forms which are commonly solitary, with the stem and pileus

scarcely 1 in. it ranges to 3 in.

On stumps. Frequent. August to October.

According to Fries the odor is weak, of anise; but it is generally

strong and very pleasant. _Stevenson._

=Spores= nearly globular, 4µ diameter _Morgan_; spheroid or

ellipsoid-spheroid, uniguttate, 4–6µ _K._; almost globular, 4µ _W.G.S._

The dense clusters of all sized members are usually plenty in favored

localities. It is inviting in appearance, taste and spicy odor. It

retains a suspicion of the latter when cooked which gives the dish a

flavor pleasant to many. It must be young to be tender. When dry—like

others of its kind—it can be grated and used in many ways.

=L. Un´derwoodii= Pk. =Pileus= fleshy, tough, convex or nearly plane,

the glabrous surface cracking into areola-like scales which are

indistinct or wanting toward the margin, whitish or slightly tinged with

buff or pale ochraceous. =Flesh= white. =Gills= moderately close,

decurrent, slightly connecting or anastomosing at the base, somewhat

notched on the edge, whitish, becoming discolored in drying. =Stem=

stout, hard, solid, eccentric, squamose, colored like the pileus.

=Spores= oblong, 13–15×5–6.5µ.

=Plant= cespitose. =Pileus= 3–6 in. broad. =Stem= 1.5–3 in. long, about

1 in. thick.

This differs from L. magnus in its cespitose habit, eccentric stem,

longer spores, less distinctly areolate-squamose pileus and in its

habitat. The gills are connected at the base very much like those of

Pleurotus ostreatus. _Peck_, Torr. Bull. Vol. 23, No. 10.

North Carolina, Pennsylvania, _McIlvaine_.

The writer first met with it in North Carolina, near Washington, on oaks

and railroad timbers, and in Fairmount Park, Philadelphia. It attains

quite a size, grows singly and in clusters. Its clean, cake-like

appearance is attractive. Cooked it ranks with P. ulmarius, L. lepideus,

and Panus strigosus.

ANALYSIS OF SPECIES.

* Stem excentric.

** Stem lateral.

*** Stem absent. Pileus resupinate or dimidiate.

Species of this genus are among our most observable fungi. Their

settlements are frequent on decaying trees, stumps, branches, on fences,

cut timber, etc. Most of them are small, but their coriaceous build

prevents their shrinking in cooking. Most species have a pleasant

farinaceous taste and odor, which they yield, together with a gummy

substance, to soups and gravies.

Tasting a small piece will immediately tell, if the species is not

known, whether it is edible or of the styptic kind.

* _Stem excentric._

=P. concha´tus= Fr.—Formed like _concha_, a shell-fish. =Pileus= about 3

in. across, tough and flexible, unequal, excentric or dimidiate, margin

often lobed, cinnamon-color becoming pale, at length more or less scaly.

=Flesh= thin. =Gills= narrow, forming decurrent lines on the stem,

somewhat branched; pinkish-white then pale-ochraceous. =Stem= about ⅔

in. long, 3–4 lines thick, solid, unequal, pale, base downy. _Massee._

On trunks of beech, poplar, etc.

Often imbricated and more or less grown together. Allied to Panus

torulosus, but distinguished by the much thinner pileus, more expanded

and excentric, also dimidiate, flaccid, cinnamon becoming pale, but the

form not constant. =Stem= about ½ in. long, 4 lines thick, often

compressed, downy at the base. =Pileus= 2–4 in. broad, scaly when old.

=Gills= decurrent in long, parallel lines, not at all resembling those

of Pleurotus ostreatus, which anastomose behind, but frequently

unequally branched, at first whitish or pale flesh-color, then

wood-color, crisped when dry. _Fries._

Always known by its shell-like form and its tough substance.

Sent to the writer by Mr. E.B. Sterling, Trenton, N.J. September, 1898.

The appearance of scales upon the pileus was scarcely noticeable. Taste

pleasant. The fungus is tough when old, but yields an excellent gravy.

A most distinct species, remarkable for its great lightness when dry and

the long villous but not compressed or compound flocci of the pileus.

Sometimes the center of the pileus becomes quite smooth when old.

One of the prettiest of fungi. The markings upon the white margin are

more precise than those of the finest bee comb. One does not tire

looking at the work of Nature’s geometrician. It is not plentiful, but

is of useful size. It has good flavor and cooks quite tender.
